Rihanna Bares Butt on Instagram [Pic]

Rihanna loves to pose topless, but she decided to show off her other end and bared her butt on Instagram. Get up close and personal with RiRi's rear.

The snap has since been removed from her feed, but not before the Internet spread it around like an infectious disease.

The shot features the singer's bare, shapely butt, wearing what could have once been booty shorts and/or jeans, and a dental floss thong that looks super uncomfy.

Ri's bootay is right up in ya grill! That's a derriere that won't quit.

She is shooting the video for 'Pour It Up' and had Instagrammed a pic of stripper heels and singles, all tools of an exotic dancer's trade. Perhaps the video inspired her to booty bounce and share it with the digi world?
